Question

Discuss cell surface transport under the following headings structure-constituents

Answer 1

(i)noun. A constituent is described as someone who has the potential to appoint some other person to be a consultant. An example of constituent is a registered voter.

(ii)Cells might have slender extensions of the cytomembrane to create cilia or the smaller extensions referred to as microvilli. The microscopic microvilli effectively increase the extent of the cell and are helpful for absorption and secretion functions. A dramatic example is that the human bowel.

(iii) Sperm tails and cartilaginous tube cilia from Polynesians with bronchiectasis were examined within the microscope. The outer jacket tubules of the axonemal skeleton in these organelles either lacked dynein arms or had solely partial arms. numerous alternative organelle abnormalities were common. The spermatozoan were immobile and pulmonic mucociliary clearance was reduced or absent.

Answer 2

Cell surface transportation or membrane

transport is defined as the collection of

mechanisms that regulate the passage of

solutes such as ions and small molecules

through biological membranes, which are lipid

bilayers that contain proteins embedded in the

layers between them. The movement of the

substance is via the transportation proteins

which helps in the transportation of the

substance in the layers of the cells.
